The co-optimization of floral display and nectar reward

open access: yesJournal of Biosciences, 2009
In most insect-pollinated flowers, pollinators cannot detect the presence of nectar without entering the flower. Therefore, flowers may cheat by not producing nectar and may still get pollinated. Earlier studies supported this 'cheater flower' hypothesis and suggested that the cost saving by cheater flowers could be the most predominant selective force

Chronic intake of fermented floral nectar by wild treeshrews [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
For humans alcohol consumption often has devastating consequences. Wild mammals may also be behaviorally and physiologically challenged by alcohol in their food. Here, we provide a detailed account of chronic alcohol intake by mammals as part of a coevolved relationship with a plant.

Impacts of soil nutrition on floral traits, pollinator attraction, and fitness in cucumbers (Cucumis sativus L.)

open access: yesScientific Reports, 2022
Annual plants allocate soil nutrients to floral display and pollinator rewards to ensure pollination success in a single season. Nitrogen and phosphorus are critical soil nutrients whose levels are altered by intensive land use that may affect plants ...

Agronomic Traits in Oilseed Rape (Brassica napus) Can Predict Foraging Resources for Insect Pollinators

open access: yesAgronomy, 2021
Mass-flowering crops, such as oilseed rape (OSR; Brassica napus), provide pulses of nectar and pollen, helping to support pollinators and their pollination services in agricultural landscapes.

Floral Trait Variations Among Wild Tobacco Populations Influence the Foraging Behavior of Hawkmoth Pollinators

open access: yesFrontiers in Ecology and Evolution, 2018
Most pollinators visit flowers in the search of nectar rewards. However, as the floral nectar can often not be directly detected by pollinators, many flower visitors use secondary metabolites such as odor- or taste-proxies to anticipate nectar quantity ...

Nectar-dwelling microbes of common tansy are attractive to its mosquito pollinator, Culex pipiens L.

open access: yesBMC Ecology and Evolution, 2021
Background There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect ...

Caffeine in Floral Nectar Enhances a Pollinator's Memory of Reward [PDF]

open access: yesScience, 2013
Bees Get That Caffeine "Buzz" Caffeine improves memory in humans, millions of whom find that their daily dose enhances clarity, focus, and alertness. The human relationship with caffeine is relatively recent, however, and thus its impact on our brains is likely a by-product of its true ecological role.

The Campsis-Icterus association as a model system for avian nectar-robbery studies

open access: yesScientific Reports, 2022
Avian nectar-robbing is common in some floras but its impact on plant-pollinator mutualisms, flowering phenology, and the evolution of floral traits remains largely unexplored.
